Name that Bullet

A couple of bloggers Snapped Shot and Confederate Yankee are trying to figure out the type of bullet she's holding. A few guesses have been:

M903/M962 SLAP









This might be a bit too big. Also the SLAP isns't as round as the bullet pictured in the womans hand.









Others siad 7.62mm









This also is close.







How about .408 Chey Tac



















M48?

If you ask me, I think its never been fired from a weapon. It looks like some sort of .50 black powder bullet. I doubt black powder weapons are that common over there. But it's just a guess. Maybe the photographer had it in his pocket and handed it to her.















Here's a closeup of the bullet in question:
